4.2 FKR-EU with fusible link and limit
switch, explosion-proof version
NOTICE!
The Z-plate ( Fig. 1 /10.21) is an important compo-
nent of the ATEX version of the FKR-EU with fusible
link, which ensures a conductive connection between
the thermal release device and the fire damper
casing.
When installing the thermal release device on the fire
damper casing, be sure to insert one of the two fixing
screws into the circular hole of the Z-plate.
When removing the thermal release device (Ä FKR-
EU operating and assembly instructions), check that
the Z-plate is intact. If damaged, replace the entire
thermal release device.
The Z-plate must not be changed or removed.
